An outdoor area LED lighting system including: a housing containing a large array of LEDs mounted to an aluminum direct thermal path printed circuit board and a single lens. The large array of LEDs are capable of producing light rays directed through the single lens to produce a beam of light to illuminate the outdoor area. The single lens is preferably a Fresnel lens. The housing is preferably capable of being sealed in a weather-tight manner. A second housing may at least partially surround the first housing such that at least one air passage is provided between the first housing and the second housing. A heat sink including a heat block in thermal communication with a plurality of heat tubes and fin assemblies may be in partial thermal contact with the LED module and in fluid communication with the at least one air passage. At least one fan may be provided in or in fluid communication with said at least one air passage to cool the heat sink. A digital interface may connect the LED module to a host computer to monitor and track information and trending for statistical process control.
